NAIL-PLATE FEEDERl SPECIFICATION forming part of Letters Patent No.379,135, dated March 6, 1888. v

Application filed March 24, 1R87.

T all whom it may concern:

Beit known that we, SETE HARVEY SHURT- LEEF and LEwIs RUDOLPH HAAG,citizens of the United States, residing at Middleport, in

5 the county of Meigs and State of Ohio, have invented certain new anduseful Improvements in Nail-Plate Feeders; and we do hereby declare thefollowing to be a full, clear, and exact d escription of the invention,such as will enable Io others skilled in the art to which it appertainsto make and use the same.

This invent-ion relates to feeding attachments for nail-cuttingmachines,wh'ich attachments are known in the art as nail-plate feeders,and it has particular reference, first, to the construction of thebearing in which said shaft works, to permit adjustment of the latter;second, to the construction of the arm of the rock-shaft through whichthe vibration zo of the rack-standard and the oscillation of the barrelare effected; and, third, to the details of construction wherebyadjustment of parts is permitted to adapt the feeder to differentnailmachines, all as will be hereinafter described,

and pointed out in the claims.

In the accompanying drawings, which form a part of this specification,Figure 1 represents a side elevation ot so much of a feeder as isnecessary to illustrate this invention; Fig. 2,

3o a front elevation of the saddle and shaft-bear ing; Fig. 3, a planview of the same; Fig. 4, a plan and part sectional view of theshaftbearing with the cap or box removed, and Fig. 5 a detail viewshowing the construction ofthe arm of the rock-shaf.

A designates a part of the bed of a nail- Inachine to which the feederis attached, and which may be of any preferred construction.

ct a designate two right-angled brackets,

to which are adjustably attached to the bed of the machine by bolts orscrews a a', passing through slots a a2 in their vertical arms, wherebyvertical adjustment of the brackets is permitted. On the horizontal armsof the brackets is supported a transverse bar or plate, as, whichcarries the bearing a4 for the front end of the rock-shaft B.Thisvbearing a consists of a cylindrical block which has a trans-A verseopening through which the front end of o the shaft passes, as indicatedin Fig. 4. This block a4 is seated in a socket in thev plate a3,

ladjoining faces to form, when put together, an

Serial No. 232.278. (No model.)

and is secured therein by a cap, a5, which is bolted to the plate a, asshown in Fig. 2. The plate a3 and its cap a5 are each recessed on theirelongated opening which coincides with the opening through the block a,to forni a passage through all these parts for the shaft B. The blocka4, being cylindrical, is adapted to turn in its seat in the plate a3and cap a? when for any reason it is desired to make a lateraladjustment at the rear end of the shaft B, which adjustment is alsopermitted by the elongated opening formed in t-he plate and cap cias'.The plate ais clamped to the brackets c a by clamp screws or bolts a,which pass through enlarged openings in the bracket-arms, whereby anadjustment of the plate in `any direction in a horizontal plane ispermitted.

The shaft B is secured against longitudinal movement by its arm E on oneside of the plate a3 and by a collar, b', on the opposite side. Theadjustability of these parts on the shaft, however, permits alongitudinal adjustment of the shaft when desired.

E designates the arm of the rock-shaft B, through which the vibration ofthe rackstandard F and its rack G is effected to impart oscillatorymotion to the barrel in the usual manner.

To adjust the feeder to different machines it sometimes becomesnecessary to raise or lower the barrel by using a longer or shorterbarrelstock, and in such cases it also becomes necessary to use acorrespondingly longer or shorter arm on the rockshaft, in order thatthe proper degree of oscillation of the barrel may be maintained.Therefore in order that such adjustments may be made without thenecessity of taking of the arm and substitut- J ing another of therequisite length, we make it adjustable, such adjustability beingprovided for as follows: The arm E is made in two main parts, (marked eand e.) The parte has in its upper end a socket, into which the parteflts, 9: and in which it is adjustable vertically, being held inadjusted position by a set-screw, e, whereby the arm is permitted to belengthened or shortened at pleasure to effect the proper adjustment. Itis also sometimes nec essary or desirable to adjust the arm radially orlongitudinally, or both, on the shaft B, and

IOO

the saddle, as indicated in Fig. 3.

, itself, as indicated in Fig. 5.

to provide for such adjustment the lower end of the part cis formed witha clamp-socket, which receives shaft. This clampsocket is formed bybending the metal around upon Then by means of a screw, e3, the clampthus formed is tightened and the arm securely fastened on the shaft. Inpractice this is found far superior to the ordinary set-screw, for thereason that it is not only stronger, but it permits the arm to besecurely fastened after the slightest adjustment, whereas the point ofthe set-screw, after forming a scat in the shaft, is apt to slip backinto such seat unless the adjustment is sufficient to carry it entirelyaway therefrom, thus practically preventing the finer adjustlnents ofthemachine.

C designates the saddle, which is mounted between ears or bearinglugs a7a? at the ends ofthe plate a. being held therein by pointed screws c c',which pass through said ears and extend into cavities or sockets in theends of The screws c form pivots, upon which the saddle is allowed torock to effect a vertical adjustment of the barrel, as will behereinafter described. The saddle is curved or bent at its center topass around the bearing at, and it has two forwardly-extendinghorizontal arms, c'l c2, between the ends of which is arranged a shaft.D, which is secured in position by pointed screws c c", passing throughthe arms and entering cavities in its ends, as also shown in Fig. 3.These screws also form pivots upon which the shaft D may turn.

d d are two lugs on the shaft D, upon which is bolted the foot of thebarrel'stock H by screws d' d, which pass through said foot and screwinto said lugs, as indicated in Figs. l and 3. If the holes inthe footthrough which the screws d d pass be elongated in a horizontaldirection, the barrel stock and its barrel may be adjusted laterally;but this is not new, and need not, therefore, be shown.

By bolting the barrelstock upon the lugs d a space is left between itand the shaft D, and in this space the foot of the rack standard F issecured by a pointed screw, f, that passes through the foot of thebarrel-stock and enters a cavity in the foot of the rack-stainlard, andwhich forms a pivot upon which the said rack standard vibrates. Thebarrelstock and rack-standard, being both secu red to the shaft D, arecapable of being turned away from the machine without disengaging them.

Vertical adjustment of the barrel-stock and rackarm and their connectedparts is effected by means of a screw, c", which passes through oneofthe arms of the saddle and bears upon the horizontal arm of thebracketa.

Having thus described our invention, weA claim as newl. In a nail-platefeeder, the combination, with the brackets by which the feeder isconnected with the nailniachine and with the rock-shaft of the feeder,of a transverse bar supported on said brackets, and a bearing for therock-shaft supported by said transverse bar and capable ofadjustingitsclf toa change in the angular direction of therock-shaft,sub stantially as shown and described.
